I. Major Potential Safety Hazards
1. Unapproved special construction schemes and incomplete safety technical disclosure for all operators.
2. Unlicensed workers working on site without wearing safety helmets, safety belts and anti-slip shoes.
3. Unqualified steel pipes and fasteners; irregular application of channel steel and unfixed cantilever steel beams without steel wire ropes for cantilever scaffolding.
4. Incomplete or improperly installed protective facilities including dense safety nets and horizontal safety nets.
5. Over-standard vertical pole spacing, lapped vertical poles and concentrated joints on the same horizontal plane.
6. Irregularly installed or missing bottom sweeping ledgers, as well as misplaced and insufficient horizontal ledgers.
7. Insufficient wall connectors and non-standard diagonal braces; unauthorized removal of frame members and fasteners.
8. Incompletely laid scaffold boards at the base and working layers.
II. Three Typical Scaffolding Accidents
1. Falling accidents from height
2. Injury accidents caused by falling objects
3. Overall overturning of scaffolding frame
III. Standard Risk Prevention and Control Measures
1. Complete compilation, approval of construction schemes and signed safety technical disclosure before construction.
2. Implement certified-post system; all workers shall wear full protective equipment during operation.
3. Adopt qualified steel pipes and fasteners; forbid channel steel use and fix cantilever beams with steel wire ropes strictly.
4. Install and fasten dense safety nets and horizontal safety nets in full compliance with construction codes.
5. Follow designed pole spacing strictly; forbid pole lapping and concentrated horizontal joints.
6. Arrange sweeping ledgers and horizontal ledgers fully in accordance with construction specifications.
7. Equip sufficient wall connectors and diagonal braces; prohibit random demolition of any frame components.
8. Lay scaffold boards fully and firmly on both base and working layers as required.
